一种投屏方法、设备、存储介质及计算机程序产品Screen projection method, device, storage medium and computer program product

技术领域technical field

本申请涉及计算机技术领域，具体地涉及一种投屏方法、设备、存储介质及计算机程序产品。The present application relates to the field of computer technology, and in particular to a screen projection method, device, storage medium and computer program product.

背景技术Background technique

在现有技术的应用场景中，多屏协同是一种分布式技术，可以实现跨系统、跨设备之间的协同操作，将手机与电脑、平板或者平板与电脑连接后，实现跨设备的资源共享及操作。In the application scenarios of existing technologies, multi-screen collaboration is a distributed technology that can realize cross-system and cross-device collaborative operations. After connecting mobile phones to computers, tablets or tablets to computers, cross-device resources Share and operate.

多屏协同的一种应用场景是无线投屏，无线投屏通常指：通过无线网络，将具有较强核心处理能力的源多媒体终端的屏幕显示内容以流媒体的形式实时地传送到目的多媒体终端上进行显示的技术。源端主要指手机等具有较强独立核心处理系统的可移动智能设备，服务终端指的是多媒体服务终端，包括支持屏幕接收且具备较好的视听效果的平板、电子白板、大屏幕以及电视等。通过无线投屏，可将手机/平板内容或媒体文件(图库、音乐和视频)投射到大屏上，获得跨屏体验。例如，2019年8月华为开发者大会EMUI10上发布多屏协同，实现PC和手机的无缝协同。2019年11月25日华为MatePad及全场景发布会，正式发布旗舰新品MatePad Pro平板电脑，MatePad Pro搭载EMUI10系统，支持多屏协同功能，可将手机屏幕直接投射到平板上。An application scenario of multi-screen collaboration is wireless projection. Wireless projection usually refers to: the screen display content of the source multimedia terminal with strong core processing capabilities is transmitted to the destination multimedia terminal in real time in the form of streaming media through a wireless network. display technology. The source end mainly refers to mobile smart devices with strong independent core processing systems such as mobile phones, and the service terminal refers to multimedia service terminals, including tablets, electronic whiteboards, large screens, and TVs that support screen reception and have good audio-visual effects. . Through wireless screen projection, mobile phone/tablet content or media files (gallery, music and video) can be projected to the large screen to obtain a multi-screen experience. For example, in August 2019, the Huawei Developer Conference EMUI10 released multi-screen collaboration to achieve seamless collaboration between PCs and mobile phones. On November 25, 2019, Huawei MatePad and its full-scenario press conference officially released the flagship new MatePad Pro tablet computer. MatePad Pro is equipped with EMUI10 system, supports multi-screen collaboration function, and can directly project the screen of the mobile phone to the tablet.

在无线投屏应用场景中，投屏反向控制(user input back channel，UIBC)通常指：通过无线投屏接收端控制发送端设备的一种功能，它允许用户在投屏下使用接收端的输入设备控制手机/平板。不同投屏设备，可用的输入设备不同，包括键盘、鼠标、遥控器、触屏等。In the application scenario of wireless screen projection, reverse screen projection control (user input back channel, UIBC) usually refers to: a function that controls the sending end device through the wireless projection screen receiving end, which allows the user to use the input of the receiving end under the screen projection Device control phone/tablet. Different screen projection devices have different available input devices, including keyboard, mouse, remote control, touch screen, etc.

在UIBC应用场景中，用户通过无线投屏接收端控制发送端设备，由于响应用户控制操作的实际执行设备为发送端设备，因此，在用户在无线投屏接收端进行控制操作与无线投屏接收端显示该控制操作的响应结果之间的时延，会远远大于，用户直接在发送端设备进行控制操作与发送端设备直接显示该控制操作的响应结果之间的时延，这就大大降低了用户的设备使用体验。因此，需要一种新的投屏方案，以减小用户在无线投屏接收端进行控制操作与无线投屏接收端显示该控制操作的响应结果之间的时延。In the UIBC application scenario, the user controls the sending end device through the wireless projection receiving end. Since the actual execution device responding to the user's control operation is the sending end device, the user performs the control operation and the wireless projection receiving end at the wireless projection receiving end. The time delay between displaying the response result of the control operation at the end will be much greater than the time delay between the user directly performing the control operation on the sending end device and the sending end device directly displaying the response result of the control operation, which greatly reduces the user's device experience. Therefore, a new screen projection solution is needed to reduce the time delay between the user's control operation at the wireless screen projection receiving end and the wireless screen projection receiving end displaying the response result of the control operation.

基于图5所示实施例，虽然可以在手机401投屏平板电脑402的应用场景中实现在平板电脑402上控制手机401(UIBC)，但是，在UIBC的控制流程中，平板电脑402需要将平板侧的用户触控时间发送到手机401，待手机401上的应用响应后，对手机屏幕进行录制和编码，再将编码结果返回给平板电脑402。相较于用户直接在手机401控制应用，执行UIBC，用户在平板电脑402上进行操作到平板电脑402显示应用响应画面间的时延被大大延长。Based on the embodiment shown in FIG. 5 , although it is possible to control the mobile phone 401 (UIBC) on thetablet computer 402 in the application scenario where themobile phone 401 casts a screen on thetablet computer 402, in the UIBC control process, thetablet computer 402 needs to use the tablet The touch time of the user on the side is sent to themobile phone 401, and after the application on themobile phone 401 responds, the screen of the mobile phone is recorded and encoded, and the encoding result is returned to thetablet computer 402. Compared with the user directly controlling the application on themobile phone 401 and executing the UIBC, the time delay between the user operating on thetablet computer 402 and thetablet computer 402 displaying the application response screen is greatly extended.

例如，在某一多屏协同特性反控应用场景中，用户通过被投屏设备(例如平板电脑)反向控制投屏设备(例如手机)的时延约为140ms+，而用户直接进行本地操控(直接操作手机)时延为40ms。For example, in an anti-control application scenario with multi-screen collaborative features, the time delay for the user to reversely control the projected device (such as a mobile phone) through the projected device (such as a tablet) is about 140ms+, while the user directly performs local control ( Directly operate the mobile phone) the delay is 40ms.

进一步的，在图5所示的UIBC流程中，手机401上的应用(APP01)编码后的数据是通过网络(Network)发送到平板电脑402，因此，当网络较差或波动较大时，时延会进一步加大，会很容易出现操作卡顿，影响最终用户操控体验。并且，在图5所示的UIBC流程中，相较于用户直接在手机401控制应用，手机401在通过APP01执行响应的同时还需要进行屏幕内容录制、编码以及发送，这会额外增加手机401的功耗。Further, in the UIBC process shown in Figure 5, the data encoded by the application (APP01) on themobile phone 401 is sent to thetablet computer 402 through the network (Network). Therefore, when the network is poor or fluctuates greatly, when The delay will be further increased, and the operation will be prone to freeze, which will affect the end user's control experience. Moreover, in the UIBC process shown in Figure 5, compared with the user directly controlling the application on themobile phone 401, themobile phone 401 needs to record, encode and send the screen content while executing the response through APP01, which will additionally increase the cost of themobile phone 401. power consumption.

In some application scenarios, an application (APP02) consistent with an application (for example, APP01) currently running on the screen-casting device (for example, a mobile phone 401) is also installed on the screen-casting device (for example, a tablet computer 402), APP02 and APP01 are different versions of the same application (for example, application A) targeting different types of devices. APP02 has the same function as APP01, the difference is that APP01 is installed onmobile phone 401, and APP02 is installed ontablet computer 402. In this way, when the user operates the application (APP01) currently running on the screen projection device (mobile phone 401) on the screen projection window of the screen projection device (for example, the screen projection window 403), the user can directly use the screen projection device ( The APP02 installed on the tablet computer 402) responds to the user's operation, thereby reducing the operation delay and reducing the power consumption of the screen projection device (mobile phone 401) on the basis of ensuring the user's application operation experience.

具体的，在一实施例中，在S833中，平板电脑702的应用内容同步模块监听平板电脑702聊天应用(应用A，APP02)根据用户的输入事件进行响应的响应过程中对平板电脑702的聊天应用(应用A，APP02)本地文件/路径(例如：File、FileInputStream、FileOutputStream、BitmapFactory)的访问(S834)。当平板电脑702的聊天应用(应用A，APP02)在响应用户输入事件的过程中尝试访问相关路径或文件时，平板电脑702的应用内容同步模块将访问请求(同步请求)发送到手机701的应用内容读取模块(S835)。手机701的应用内容读取模块接收平板电脑702的应用内容同步模块发来的文件访问请求后，实时读取手机701上对应文件访问请求的聊天应用(应用A，APP01)本地应用数据(S836)，加密后发送到平板电脑702的应用内容加载同步模块。Specifically, in one embodiment, in S833, the application content synchronization module of thetablet computer 702 listens to the chatting of thetablet computer 702 during the response process in which the chat application (application A, APP02) of thetablet computer 702 responds to the input event of the user. The application (Application A, APP02) accesses local files/paths (for example: File, FileInputStream, FileOutputStream, BitmapFactory) (S834). When the chat application (application A, APP02) of thetablet computer 702 tries to access the relevant path or file in the process of responding to the user input event, the application content synchronization module of thetablet computer 702 sends the access request (synchronization request) to the application of the mobile phone 701 A content reading module (S835). After receiving the file access request sent by the application content synchronization module of thetablet computer 702, the application content reading module of themobile phone 701 reads the local application data of the chat application (application A, APP01) corresponding to the file access request on themobile phone 701 in real time (S836) , the encrypted application content sent to thetablet computer 702 is loaded into the synchronization module.

平板电脑702的应用内容加载同步模块接收手机701的应用内容读取模块发来的应用数据后，进行解密，解密后提供给平板电脑702的聊天应用(应用A，APP02)进行加载(S837)，从而使得平板电脑702的聊天应用(应用A，APP02)基于手机701的应用数据对用户的输入事件进行响应。After the application content loading synchronization module of thetablet computer 702 receives the application data sent by the application content reading module of themobile phone 701, it decrypts, and after decryption, it is provided to the chat application (application A, APP02) of thetablet computer 702 to load (S837), Thus, the chat application (application A, APP02 ) of thetablet computer 702 responds to the user's input event based on the application data of themobile phone 701 .

在S833之后，平板电脑702上聊天应用(应用A，APP02)的显示内容为针对用户输入事件的响应结果。由于用户输入事件并未同步传输到手机701，手机701上的聊天应用(应用A，APP01)并未执行响应操作，因此，如果在S813中，手机701的屏幕显示内容为聊天应用(应用A，APP01)的启动界面。那么，在S833之后，手机701的屏幕显示内容保持在聊天应用(应用A，APP01)的启动界面。After S833, the display content of the chat application (Application A, APP02) on thetablet computer 702 is the response result to the user input event. Since the user input event is not synchronously transmitted to themobile phone 701, the chat application (application A, APP01) on themobile phone 701 does not perform a response operation. Therefore, if in S813, the content displayed on the screen of themobile phone 701 is the chat application (application A, APP01) APP01) startup interface. Then, after S833, the content displayed on the screen of themobile phone 701 remains at the startup interface of the chat application (Application A, APP01).

进一步的，在S833中，在平板电脑702的聊天应用(应用A，APP02)响应用户的输入事件的过程中，聊天应用的应用数据可能会被改写(例如，增加了新的聊天记录、保存了新的聊天图片、设定了新的聊天背景等等)。因此，在一实施例中，在S833之后，平板电脑702的应用内容同步模块将S834中生成的新的应用数据发送到手机701的应用内容读取模块。手机701的应用内容读取模块使用接收到的应用数据更新手机701上对应的本地应用数据。Further, in S833, during the process of the chat application (application A, APP02) of thetablet computer 702 responding to the user's input event, the application data of the chat application may be rewritten (for example, adding a new chat record, saving new chat picture, set a new chat background, etc.). Therefore, in an embodiment, after S833, the application content synchronization module of thetablet computer 702 sends the new application data generated in S834 to the application content reading module of themobile phone 701. The application content reading module of themobile phone 701 uses the received application data to update the corresponding local application data on themobile phone 701 .

进一步的，为了避免用户个人隐私数据泄露，在S833之后，平板电脑702的应用内容同步模块删除手机701的应用内容读取模块发送过来的应用数据。具体的，平板电脑702的应用内容同步模块可以在聊天应用(应用A，APP02)每次响应完成后删除应用数据，也可以在聊天应用(应用A，APP02)运行结束、被关闭后删除应用数据，也可以在投屏操作结束后再删除应用数据。Further, in order to avoid leakage of the user's personal privacy data, after S833, the application content synchronization module of thetablet computer 702 deletes the application data sent by the application content reading module of themobile phone 701.

进一步的，在另一实施例中，在S821之前，平板电脑702的应用内容同步模块将针对聊天应用(应用A，APP02)同步请求发送到手机701的应用内容读取模块。手机701的应用内容读取模块接收平板电脑702的应用内容同步模块发来的同步请求后，实时读取手机701上聊天应用(应用A，APP02)在启动以及启动后运行过程中可能访问的所有本地应用数据，加密后发送到平板电脑702的应用内容加载同步模块。Further, in another embodiment, before S821, the application content synchronization module of thetablet computer 702 sends a synchronization request for the chat application (application A, APP02) to the application content reading module of themobile phone 701. After receiving the synchronization request sent by the application content synchronization module of thetablet computer 702, the application content reading module of themobile phone 701 reads in real time all chat applications (application A, APP02) on themobile phone 701 that may be accessed during startup and running after startup. The local application data is encrypted and sent to the application content loading synchronization module of thetablet computer 702 .

平板电脑702的应用内容加载同步模块接收手机701的应用内容读取模块发来的应用数据后，进行解密，解密后提供给平板电脑702的聊天应用(应用A，APP02)。在平板电脑702的聊天应用(应用A，APP02)的启动过程以及启动后运行过程(响应用户输入事件)中，平板电脑702的聊天应用(应用A，APP02)加载手机701的应用数据，平板电脑702的聊天应用(应用A，APP02)基于手机701的应用数据启动并对用户的输入事件进行响应。After receiving the application data sent by the application content reading module of themobile phone 701, the application content loading synchronization module of thetablet computer 702 decrypts, and provides the chat application (application A, APP02) of thetablet computer 702 after decryption. In the startup process of the chat application (application A, APP02) of thetablet computer 702 and the running process after startup (in response to user input events), the chat application (application A, APP02) of thetablet computer 702 loads the application data of themobile phone 701, and the tablet computer The chat application (Application A, APP02) of 702 starts based on the application data of themobile phone 701 and responds to the user's input event.

可以理解的是，上述实施例中的部分或全部步骤或操作仅是示例，本申请实施例还可以执行其它操作或者各种操作的变形。此外，各个步骤可以按照上述实施例呈现的不同的顺序来执行，并且有可能并非要执行上述实施例中的全部操作。It can be understood that some or all of the steps or operations in the foregoing embodiments are only examples, and other operations or modifications of various operations may also be performed in the embodiment of the present application. In addition, various steps may be performed in different orders presented in the above embodiments, and it may not be necessary to perform all operations in the above embodiments.

进一步的，一般的，对于一个技术的改进可以很明显地区分是硬件上的改进(例如，对二极管、晶体管、开关等电路结构的改进)还是软件上的改进(对于方法流程的改进)。然而，随着技术的发展，当今的很多方法流程的改进已经可以视为硬件电路结构的直接改进。设计人员几乎都通过将改进的方法流程编程到硬件电路中来得到相应的硬件电路结构。因此，不能说一个方法流程的改进就不能用硬件实体模块来实现。例如，可编程逻辑器件(Programmable Logic Device,PLD)(例如现场可编程门阵列(Field ProgrammableGate Array，FPGA))就是这样一种集成电路，其逻辑功能由访问方对器件编程来确定。由设计人员自行编程来把一个数字装置“集成”在一片PLD上，而不需要请芯片制造厂商来设计和制作专用的集成电路芯片。而且，如今，取代手工地制作集成电路芯片，这种编程也多半改用“逻辑编译器(logic compiler)”软件来实现，它与程序开发撰写时所用的软件编译器相类似，而要编译之前的原始代码也得用特定的编程语言来撰写，此称之为硬件描述语言(Hardware Description Language，HDL)，而HDL也并非仅有一种，而是有许多种，如ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware DescriptionLanguage)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL(RubyHardware Description Language)等，目前最普遍使用的是VHDL(Very-High-SpeedIntegrated Circuit Hardware Description Language)与Verilog。本领域技术人员也应该清楚，只需要将方法流程用上述几种硬件描述语言稍作逻辑编程并编程到集成电路中，就可以很容易得到实现该逻辑方法流程的硬件电路。Further, in general, improvements to a technology can be clearly distinguished as improvements in hardware (for example, improvements to circuit structures such as diodes, transistors, and switches) or improvements in software (improvements to method flow). However, with the development of technology, the improvement of many current method flows can be regarded as the direct improvement of the hardware circuit structure. Designers almost always get the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be realized by hardware physical modules. For example, a programmable logic device (Programmable Logic Device, PLD) (such as a field programmable gate array (Field Programmable Gate Array, FPGA)) is such an integrated circuit, the logic function of which is determined by the programming of the device by the accessing party. It is programmed by the designer to "integrate" a digital device on a PLD, instead of asking a chip manufacturer to design and manufacture a dedicated integrated circuit chip. Moreover, nowadays, instead of making integrated circuit chips by hand, this kind of programming is mostly realized by "logic compiler (logic compiler)" software, which is similar to the software compiler used when program development and writing, but before compiling The original code of the computer must also be written in a specific programming language, which is called a hardware description language (Hardware Description Language, HDL), and there is not only one kind of HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language) , AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., currently the most commonly used is VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. It should also be clear to those skilled in the art that only a little logical programming of the method flow in the above-mentioned hardware description languages and programming into an integrated circuit can easily obtain a hardware circuit for realizing the logic method flow.

因此，本申请实施例所提出的方法流程可以以硬件方式实现，例如，使用控制器，控制器控制触摸屏以实现本申请实施例所提出的方法流程。Therefore, the method flow proposed in the embodiment of the present application may be implemented in hardware, for example, using a controller, and the controller controls the touch screen to implement the method flow proposed in the embodiment of the present application.

控制器可以按任何适当的方式实现，例如，控制器可以采取例如微处理器或处理器以及存储可由该(微)处理器执行的计算机可读程序代码(例如软件或固件)的计算机可读介质、逻辑门、开关、专用集成电路(Application Specific Integrated Circuit，ASIC)、可编程逻辑控制器和嵌入微控制器的形式，控制器的例子包括但不限于以下微控制器：ARC 625D、Atmel AT91SAM、Microchip PIC18F26K20以及Silicone Labs C8051F320，存储器控制器还可以被实现为存储器的控制逻辑的一部分。本领域技术人员也知道，除了以纯计算机可读程序代码方式实现控制器以外，完全可以通过将方法步骤进行逻辑编程来使得控制器以逻辑门、开关、专用集成电路、可编程逻辑控制器和嵌入微控制器等的形式来实现相同功能。因此这种控制器可以被认为是一种硬件部件，而对其内包括的用于实现各种功能的装置也可以视为硬件部件内的结构。或者甚至，可以将用于实现各种功能的装置视为既可以是实现方法的软件模块又可以是硬件部件内的结构。The controller may be implemented in any suitable way, for example the controller may take the form of a microprocessor or processor and a computer readable medium storing computer readable program code (such as software or firmware) executable by the (micro)processor , logic gates, switches, application specific integrated circuits (Application Specific Integrated Circuit, ASIC), programmable logic controllers and embedded microcontrollers, examples of controllers include but are not limited to the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20 and Silicone Labs C8051F320, the memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art also know that, in addition to realizing the controller in a purely computer-readable program code mode, it is entirely possible to make the controller use logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded The same function can be realized in the form of a microcontroller or the like. Therefore, such a controller can be regarded as a hardware component, and the devices included in it for realizing various functions can also be regarded as structures within the hardware component. Or even, means for realizing various functions can be regarded as a structure within both a software module realizing a method and a hardware component.
